Get it? "truth, yo," because the name of the brand is "yotruth." Haha! Yeah, maybe that's a little corny... But I couldn't help myself. I'm in a good mood for a change, which is in large part thanks to how much this power bank has impressed me. I wasn't too overly excited at first though. But that's just because a battery with a capacity of 5000mAh is kind of small for a power bank, and I don't usually have a use for power banks of that size.However, this power bank is one of a kind, and it is truly unique. Normally, I would say to only charge cell phones with a power bank that has a 5000mAh battery, if it is absolutely necessary. Because most of the flagship cell phones out there have batteries with a capacity of 5000mAh or close to it. So charging one with a power bank of this size would be all that you would charge with it. Well, that's obviously not the case with this power bank.Compared to other little power banks with solar chargers, this one can charge itself relatively quickly with solar energy. In ideal conditions it can charge at a rate of 10 watts, which would only take around 3 hours to fully charge. And that really isn't that bad at all when it comes to charging something using only solar energy. Also, as long as you have a charger capable of outputting at least 18 watts, this power bank can also be charged at a rate of 18 watts. And THAT would only take about an hour and a half or so to fully charge the battery.That's really what makes this power bank so great too. I have another power bank with a small area that can collect solar energy. And this power bank's battery capacity is 30,000mAh. The solar powering feature is just a gimmick on it though really and just... laughable, lol. Said power bank can also only charge at a maximum rate of 5 watts with a cord, which makes it take, oh... I don't know off-hand. But it took AT LEAST over 8 hours to fully charge. And so do a lot of things these days.Anyway, I would definitely recommend this Solar Power Bank Scroll to anyone who is considering getting it. I would also recommend to everyone to keep an eye on this brand, "yotruth." Sure, they might just be a "one hit wonder," but you never know...

I got this product to be able to recharge devices in the field or during extended power outages. This unique product has a flat solar array that is about 2.5 feet long and 7 inches wide when it is unwound. As you can see in the photos, the ends are held down by integral rubber bands that go around the ends of the round battery compartment and flashlight. The solar array itself is very thin, which are not as efficient as bulkier and heavier solar cells in flat panels, and so it take longer for this battery to charge and it requires bright sunlight without clouds to be effective. The level of the charge can be determined using the LED indicator lights on one end, where USB-A and USB-C charging plugs are tucked away under a rubber flat. The opposite end of the cylinder includes a basic flashlight.The size of the unit sets it apart and the novel use of the roll-up solar cells is simply cool. As a practical matter, while the size makes it easy to carry around so it's a lot easier to use than bulkier and heavier flat panels, you'll have to leave this in bright sun for 4-5 hours to get a descent charge into it in my experience. However that would be practical when camping.I am drawn to its innovative approach and style and like it, so if you're not in a rush, I recommend it.

At first glance, this seems like a lot of money for such a small output power bank. The capacity is only 5000mAh. Most powerbanks have considerably more capacity for the size and weight. Also, the flashlight is very basic and the brightness levels aren't very different, it's really just an added feature. And the surface area of the solar panel isn't as efficient as other types of solar panels, requiring a much larger area to generate enough charge for the power bank. I have a rigid 10-watt solar panel that's probably about 1/3 to 1/4 the size of this panel.But where this product shines is in the compact size, the flexibility of the CIGS solar panel, the ability to charge in less favorable light conditions and the overall durability and weather-resistance needed for hiking, camping, biking or other outdoor activities.This rolls up to be no bigger than a medium-sized flashlight and is pretty weather resistant. The solar panels are exceptionally flexible and rugged. It has loops that allow you to hang it up, although you won't want to hang it completely vertical if you can help it as that's not going to capture the best sunlight. Also, you don't want it twisting in the wind as it will significantly affect charging performance. I've found it's best to lay it on something with an incline facing the sun or even just flat on the ground.In even cloudy conditions I was able to charge it fully in one afternoon from completely drained by laying it across the railing of my porch. The flexible material used and it's ability to charge in poor sunlight is what makes that impressive. It's nearly cloth-like though it's thicker and a little more rigid. If they haven't already, they should make backpacks or parkas with this material so that you're able to charge a power bank in your pocket as you hike.For the price, you really need a good reason to want this. There are more affordable solutions with greater capacity and faster charging times. But they're bulky, more fragile and not all self-contained. If you're a hiker, camper, bicyclist, etc and want to carry the absolute smallest self-charging power bank that's rugged and can operate in a wide variety of weather conditions short of nighttime or badly overcast skies, this is a pretty impressive little unit and for those applications I would give it 5-stars.
